介绍
In the streets and alleys of the city, we often see all kinds of LED screens, which are large or small, high or low, adding a lot of color to the city’s landscape.
However, have you noticed that column-type 户外LED屏幕 seem to be rare? They obviously have unique functions and advantages, so why are they so scarce in the city?

1. What is a column-type outdoor LED screen?
The column-type outdoor LED screen is actually a large screen installed outdoors, and its key part is the “column.” The column is like the “leg” of this large screen, supporting the screen to stand there steadily.
1). The role of the column
- Support the screen:
The main task of the column is to hold the screen firmly so that it will not shake. After all, the screen is so large that it cannot stand on its own without a column.
- Wind and rain resistance:
The outdoor environment is very complex, with wind and rain. The column must have enough strength to keep the screen from falling in this bad weather.
- Fixed position:
The column can also fix the screen in a suitable position, such as facing the road or square so that people passing by can easily see the content on the screen.
2). Material of the column
The column is generally made of steel or concrete. Steel is lighter but has high strength and is easy to process; concrete is heavier but more durable and can be used for a long time. The specific material to be used depends on actual needs and budget.
3). The shape of the column
There are many shapes of columns. The simpler ones are cylinders or square columns。
The more complex ones can be made into various artistic shapes, such as tree trunks, or with decorative patterns, which are not only practical but also beautify the environment.
In short, the column is the “pillar” of the column-type outdoor LED display. With it, the screen can stand steadily outdoors and play its role.
2. Where are column-type outdoor LED displays generally used?
1). Traffic intersections and highways
At the intersections or highways in the city, the column-type LED display is like a “caring road sign.”
It can display traffic information. For example, if there is a traffic jam ahead, the screen will remind the driver, “There is a traffic jam ahead.
Please change lanes in advance” so that the driver can prepare in advance to avoid being stuck on the road.
In addition, it can also play some small videos about traffic safety, such as “Don’t play with your phone while driving,” to remind everyone to pay attention to safety.
In the highway service area, the screen can tell the driver what food and drink are in the rest area or what the weather is like so that the driver can also have a clear idea when driving long distances.
2). 体育馆 and large event venues
In stadiums or large event venues, the column-type LED display is like a “super forecaster.”
Outside the stadium, it will tell you the information about the game in advance, such as “Tonight at 8 o’clock, Team XX will play Team XX; the excitement is not to be missed”.
It will also tell you the ticket price so that fans can prepare in advance. At music festivals or large event venues, the screen will play exciting previews of the event.
For example, “There are many star performances tonight; come and join us,” and it can also tell the audience the process of the event so that everyone will not be in a hurry after entering.
3). Schools and 教育 机构
At the school gate or on campus, the column-type LED display is like an “information assistant.” It can tell everyone the latest school notices.
For example, “The whole school will be on holiday tomorrow” or “There will be a sports meeting this Saturday” so that everyone can know in time. It can also display school activities.
For example, the students’ sports meeting style and artistic performances allow passers-by to feel the vitality of the school.
If there are parents coming to the school, the screen can also briefly introduce the school’s situation so that they can know more about the school.
4). Industrial parks and corporate parks
In industrial parks or corporate parks, the column-type LED display is like a “park business card.” At the entrance of the park, it will play an introduction video of the park.
For example, “Welcome to XX Industrial Park, there are many high-tech companies here,” so visitors will have a good impression of the park at first sight.
In the park, the screen can display the company’s recruitment information, such as “XX company is recruiting, the treatment is super good,” and can also play some safety knowledge to remind everyone to pay attention to production safety and avoid accidents.
5). Tourist attractions
In tourist attractions, the column-type LED display is like a “tour guide assistant.” At the entrance of the scenic area, it will tell everyone the map of the scenic area.
For example, “Go to the left is the ancient building area, go to the right is the natural scenery area,” and it can also play the historical stories of the scenic area.
Such as “This happened here…” so that tourists will be interested in the scenic area before entering.
Inside the scenic area, the screen can remind everyone to pay attention to safety, such as “The mountain road is steep, be careful and drive slowly” so that everyone can have fun and feel at ease.
6). Gas stations and service areas
At gas stations or service areas, the column-type LED display is like a “caring waiter.” At the entrance of the gas station, it will tell everyone the oil price.
For example, “Today’s gasoline price is XX yuan per liter,” and it will also remind everyone of the refueling discount activities, such as “Fill up 200 yuan to get a car wash coupon”. In the service area, the screen will tell everyone the restaurant menu.
For example, “Today there is pizza…” and it will also remind everyone of the location of the rest area, such as “The rest area is on the right-hand side” so that drivers can easily find the services they need when they are resting.
3. Reasons why there are few pillar-type outdoor LED screens in cities
Pillar-type LED screens are heavy and need a solid foundation to stand. If the foundation is too soft, such as mud or loose soil, the pillars will definitely not stand steadily, and they are easy to shake or even fall down.
Although strengthening the foundation can solve the problem, the cost is too high.
Moreover, if the place is uneven, such as on a hillside or in a pothole, it is difficult to install the pillar-type display screen steadily.
Pillar-type display screens need to occupy a large open space and must be visible to people.
But the space in the city is already tight, and it is difficult to find a suitable place.
If it is installed on the roadside, it may block the way of pedestrians or affect traffic.
If it is installed near the community, it may block the sight of residents or affect the lighting. In short, it is too difficult to find a suitable place.
Nowadays, many cities have strict control over outdoor advertising, especially pillar-type advertising.
Because this kind of advertisement is too conspicuous, it may damage the overall beauty of the city or affect the traffic line of sight.
Therefore, many places do not allow the installation of column-type display screens at will, and some places even directly prohibit it.
这 亮度 of the column-type LED display screen is very high, and it is particularly dazzling at night.
If it is installed near residential areas, the light may shine into the residents’ homes and affect their rest.
This kind of light pollution problem can easily cause complaints from residents, so many places are reluctant to install this kind of display screen.
If you want to install a column-type display screen on a building, you have to consider the situation of the building itself.
For example, the building’s load-bearing capacity is not enough, and installing a display screen may crush the house.
The structure of the building is too complicated, and there is no place to install the column; after installing it, it will affect the appearance of the building.
In short, the problem of building structure also makes it difficult for column-type display screens to be used on a large scale in cities.
In short, although the column-type outdoor LED display screen looks cool, it is troublesome to install, costly, and easy to cause trouble. These factors combined make it less common in cities.
4. So, what kind of installation is suitable for LED display screens in cities?
1). Wall-mounted installation
In cities, wall-mounted LED display screens are quite popular, especially in places such as 购物广场, office buildings or subway stations.
It is like sticking the screen directly on the wall, which does not take up space and looks neat.
For example, in shopping malls, merchants can use it to display new product advertisements, and customers can see it at a glance when passing by.
The advantages of this installation method are simple and convenient, and maintenance is not troublesome. As long as the screen is broken, it can be repaired directly in front.
However, it also has disadvantages, that is, the wall must be strong enough to bear the weight of the screen. If the screen is too large and the wall is not strong enough, it will not work.
2). Suspension installation
Suspension LED display screens are like hanging the screen on the ceiling, which is especially suitable for high places such as shopping mall halls or airports.
In these places, the screen can be suspended in the air and can be seen from a long distance, attracting people’s attention.
For example, at the 飞机场, the screen can be suspended in the middle of the waiting hall to play flight information, which is convenient for passengers to see when they look up.
The advantage of this installation method is that it has a wide field of view and can cover a large area. But the disadvantage is also obvious.
You have to be very careful when installing it because the screen is hung high up, and it will be terrible if it falls.
Moreover, you have to build a scaffold or use a crane for maintenance, which is more troublesome.
3). Inlaid installation
The inlaid LED display is like embedding the screen in the wall, making the screen flush with the wall, which looks particularly beautiful.
This installation method is often used in some high-end office buildings or shopping mall facades, which can integrate the screen with the building.
For example, on the outer wall of an office building, the screen can be embedded in the glass curtain wall. It looks like glass during the day and a large screen when it lights up at night.
The advantage of this installation method is that it has a strong overall sense and looks very advanced.
However, special attention should be paid during installation because the screen has to be embedded in the wall, so enough space must be reserved for maintenance; otherwise, it will be difficult to repair the screen if it is broken.
4). Rooftop installation
The rooftop LED display is like putting the screen on the roof of a building, which is particularly suitable for outdoor advertising.
For example, on the roof of a high-rise building in a commercial area, after the screen is lit up, it can be seen from several streets around.
The advantage of this installation method is that the field of view is particularly wide, and the advertising effect is particularly good.
However, its disadvantages are also obvious. You have to be very careful when installing it because the screen is on the roof and the wind is particularly strong, so you have to consider the wind resistance.
Moreover, it is also very troublesome to maintain, and you have to climb to the roof to repair it, which has a relatively high safety risk.
5. 结论
Through the above analysis, we understand the reasons why column-type outdoor LED displays are less common in cities, and we have also found other installation methods that are more suitable for urban environments.
So, is it possible to make column-type displays revitalize cities in the future? Perhaps with the advancement of technology and the adjustment of policies, this day is not far away.
